I may not bea tech savvy person but I can say, I contribute in every little way I can. I promote Bitcoin to my family, friends and even people that i just met. I don't know but maybe they think of me as a crazy person since all I can see is all confusion in the expression of their face. But well that was during the first time I introduce Bitcoin to them. Giving them links to those sites that explain bitcoin well and guiding them to install their Bitcoin wallet. Maybe that is not as huge as other contribution but well am happy to be not the only one who uses bitcoin in our area anymore 
I've done the same thing for a while now. Promoting bitcoin to friends and family and so on.
Half of my friends are now already in bitcoin. Meaning they hold bitcoin and to some extent they even use bitcoin.
Great to hear that, start with the first around you: your friends & family. If you cant convince them, then you will have really hard time convincing strangers. Or maybe not, who knows.The point is that bitcoin is a bottom up community, and everyone has to take part, even if the contribution is small!
You are the one who is helping them for earning. This is also a way to make people self dependent.
Just give them my tutorial, it should help them get started in bitcoin. I hope more people can convince their friends, but atleast convince their family.
If you endorse bitcoin in front of them, they might be less repelled by it than if they read a demonizing mainstream article. They will know that by supporting bitcoin they will support you too, so by trashing bitcoin they would know that would make you feel bad.
